Polishing Slurry,tool,End Mills,carbide,carbide cutters,manufacturer

There are four types of BW polishing slurry :

• Polishing Slurry：

  Our polishing slurries are made with particles completely dispersed in the mixed liquids. They have fine chemical-mechanical performance and are widely used for lapping and precision polishing of silicon chips, compound crystals, optical devices, liquid crystal displays, gems, metallic works etc.

• SiO2 Slurry
  
  
• AO、CO、SC Polishing Slurry：
  BW-CO series, AO series and SC series polishing slurry are produced from superior fine abrasives. They’re suit for the super finishing of high-precision optical materials, hard disk substrates, fiber optic connectors, magnetic head, crystal compounds, ceramics, IC manufacturing etc. with good dispersibility, uniform particle size distribution, and high removal rate performance .
• Characteristics：
  • Very low impurity.
  • Good dispersing stability.
• Specifications：

• SiO2 Slurry：Chemical Mechanical Polishing (CMP) Slurries are colloidal silica liquid made of high purity de-ionized water, highly engineered chemical additives and abrasives that chemically and mechanically interact with work piece surface to remove excess materials, therefore smooth or flatten the surface. They are widely used for nanometer scale chemical mechanical polishing fields such as silicon wafers, compound crystals, optical apparatus, and sapphire polishing. The slurries have a wide range of diameter from 10 to 150 nm to meet different requirements. There are alkaline and acidic slurries based on the pH.
• Characteristics：
  1. High speed polish: with large particle of colloidal silica (Grit size up to 150 nm).
  2. Controllable size: a wide range of custom-graded colloidal silica slurries from 10 to 150 nm that suits individual needs and applications.
  3. High purity: the content of Cu2+＜50 ppb, without contamination on the work piece .
  4. Super-smooth polishing: with the particle of SiO2, avoid scratch on the object surface.
